"This means the percentage of the facility's hemodialysis patients that had the recommended urea reduction ratio (URR) of 65 or more based on the National Kidney Foundation Kidney Dialysis Outcome Quality Initiative
Why is this important?: "Patients with kidney failure need to have wastes removed from their blood often. Too much waste in your blood makes you sick. Dialysis is used to remove wastes from your blood. It is important for a facility to remove enough wastes from your blood during dialysis to help you feel better. A number known as the urea reduction ratio (URR) measures how much urea is removed during dialysis. The URR is a way to measure dialysis adequacy. Your URR should be 65 or greater."
